How do I select the appropriate laser safety window for a 200W fiber laser engraver/cutter with a 1064nm wavelength?

How do I select the appropriate laser safety window for a 200W fiber laser engraver/cutter with a 1064nm wavelength?

In most cases, the manufacturer will specify the required optical density for a laser safety window. If not, you can determine the appropriate optical density for your window by considering the wavelength and power of your laser and referring to ANSI standards.

For a 200W fiber laser with a 1064nm wavelength, we recommend one of the following products:

100-435-000: Laser Safety Window
Optical Density (OD):

OD 5+ @ 190-375 nm

OD 5+ @ 860-1095 nm

OD 6+ @ 1064 nm

OD 5+ @ 10,000-11,000 nm

100-420-000: Laser Safety Window
Optical Density (OD):

OD 5+ @ 190-375 nm

OD 5+ @ 880-1120 nm

OD 6+ @ 1064 nm

OD 5+ @ 10,000-11,000 nm
